Arch Linux: Dovecot Sieve Script Won’t Compile

• Arch Linux
• Linux kernel 4.9.36 (64-bit)
• Dovecot 2.2.31 (65cde28)
• SpamAssassin version 3.4.1 running on Perl version 5.26.0
• Pigeonhole 0.4.19-1

Trying to set up a mail server for the firs by following the Arch Linux Wiki’s Sieve tutorial (which I wound up on from following the Virtual user mail system tutorial).

This is supposed to enable spamtest and spamtestplus. Verbatim what the Wiki calls for with the exception of sieve_trace_debug and stripping out the docu-comments for legibility.

/etc/dovecot/conf.d/90-sieve.conf:

plugin {
  sieve = file:~/sieve;active=~/.dovecot.sieve

  # Start Arch Linux Wiki Config <https://wiki.archlinux.org/index.php/Dovecot#Sieve>
  sieve_extensions = +spamtest +spamtestplus

  sieve_spamtest_status_type = score
  sieve_spamtest_status_header = \
    X-Spam_score: (-?[[:digit:]]+\.[[:digit:]]).*
  sieve_spamtest_max_value = 5.0

  sieve_before = /var/lib/dovecot/sieve/global_sieves/move_to_spam_folder.sieve
  # End Arch Linux Wiki Config

  sieve_trace_debug = yes
}

This is supposed to route SPAM e-mails into a Junk folder.

/var/lib/dovecot/sieve/global_sieves/move_to_spam_folder.sieve:

require "spamtestplus";
require "fileinto";
require "relational";
require "comparator-i;ascii-numeric";

if spamtest :value "ge" :comparator "i;ascii-numeric" "5" {
  fileinto "Junk";
}

Tried to compile the above.

$ sudo sievec /var/lib/dovecot/sieve/global_sieves/move_to_spam_folder.sieve:

move_to_spam_folder: line 1: error: require command: unknown Sieve capability `spamtestplus'.
move_to_spam_folder: line 6: error: unknown test 'spamtest' (only reported once at first occurrence).
move_to_spam_folder: error: validation failed.
sievec(foo): Error: failed to compile sieve script '/var/lib/dovecot/sieve/global_sieves/move_to_spam_folder.sieve’

Didn’t work because it couldn’t find spamtest and spamtestplus. So I tested the configuration.

sudo sieve-test -t - -Tlevel=matching /etc/dovecot/conf.d/90-sieve.conf /home/foo/test.eml:

Apparently it can’t even read /etc/dovecot/conf.d/90-sieve.conf? And it’s choking on the equals sign??

It seems if I fix this error, I can enable spamtest and spamtestplus, which will in turn [potentially] fix the sievec compilation error.
